our technologyPLASMA GASIFICATION OFFERS

FLEXIBLE, EFFICIENT ENERGY RECOVERY.

With over 30 years of research and

development, and over 500,000 hours of

commercial torch operations, WPC has

developed the industry’s leading plasma

gasification technology – a highly efficient and

reliable solution. Since acquiring WPC in 2007,

Alter NRG has expanded on the development

of the technology with engineering and

operational design improvements. Testing

is also ongoing at the Westinghouse Plasma

Pilot Facility along with detailed engineering

and verification.

The WPC technology is unique in its ability

to process heterogeneous feedstock with

minimal feed preparation, allowing for the

blending of feedstocks such as municipal

waste, construction and demolition waste,

auto shredder residue, high-ash coal, biomass,

liquids and slurries. This flexibility allows

companies to optimize operations based on

available feedstocks.

The WPC plasma gasification process

yields a variety of outputs such as electricity,

steam and liquid fuels, while reducing harmful

greenhouse gas emissions. WPC plasma

gasification is a proven technology that

provides a solution for the issues of today by

maintaining the balance between energy and

the environment.

THE GASIFIER ISLAND BEHIND THE SYNGAS

Our plasma gasification island (pictured below) operates at temperatures of 5,500˚C

(10,000˚F), ensuring a complete conversion of the feedstock into syngas. The inorganic materials

are released at the base of the gasifier as an inert slag which is cooled and is a benign, non-

leachable product that can be sold as construction aggregate.

The Westinghouse Plasma gasification process is highly efficient. The overall energy recovered

from the feedstocks processed by the WPC gasifier is approximately 80%. This recovered energy

is a clean syngas that can be used to generate power, liquid fuels or other energy products.

Of the total energy needed to run the gasification process, only 2-5% of that energy is used to

power the plasma torches.

Given our equipment’s modular, scalable design, we can quickly install a plasma

gasification system anywhere, for total project costs ranging from $30 to $300 million,

making plasma technology accessible around the world.

syngas clean-upWESTINGHOUSE PLASMA PROVIDES

COMMODITY GRADE CLEAN SYNGAS.

The syngas clean-up process removes

unwanted chemicals from the syngas,

preventing harm to human health, the

environment and the facility’s equipment.

Syngas clean-up options are based upon

feedstock and syngas application (ie:

electricity or liquids). Based on the plasma

gasification facility’s inputs and end

products, the engineering, procurement

and construction for the facility will design

the optimal syngas clean-up system

based on the specific application and

configuration. One example for syngas

clean-up used in a power generation

process: upon exit from the gasification

reactor, the syngas is rapidly cooled and

particulate matter is removed by mixing

with process water in a venturi scrubber

and spray tower. Further removal of

particulates occurs in a wet electrostatic

precipitator. The temperature of the

syngas is decreased and the pressure is

increased to condense any moisture from

the syngas. Removed process water is

treated on-site to be reused within the

facility. Any mercury present is removed

as the syngas passes through activated

carbon beds with sulfur being removed

by a hydrolysis reaction and conversion

to crystals. Following this process the

syngas is used to generate power.

RECOVERY OF INORGANIC PRODUCTS

Inorganic and saleable products can be recovered from the plasma gasification

process. Ferrous iron and fine aggregate are recovered from the molten material

exiting the plasma gasification reactor, in addition to crystalline sulfur produced

through syngas clean-up. The separation of mixed metals occurs when the molten

material from the reactor is discharged into a quench bath. This results in metal

modules which are then separated from the aggregate. The remaining slag material,

consisting of a wide range of elements, primarily silica, can be used in numerous

construction applications and products. All materials recovered add commercial

value to the plasma gasification process.
